Description
RESET
CMD
ST
Reset.
The devices enter stanby status when a low level is input to this pin.
When RESET, oscillation stops. The AOUT output goes to ground and the IC
status is reinitialized. The devices have an internal power-on reset. V
DD
must be
raised within 1 ms to operate power-on reset correctly. If V
DD
is not raised within
1 ms, then the
RESET
pulse must be applied when power is turned ON.
This pin has an internal pull-up resistor.
Busy.
Outputs a "L" level during playback and a "H" level when power is turned ON.
The CMD and ST inputs become effective when high. NAR indicates whether the
address bus (I0 through I6) is ready to accept another address. When high, it is
ready to accept. NAR goes high when power is turned ON.
Analog Speech Output.
D/A converter output or LPF output is selected by
entering the command.
Ceramic Oscillator Input.
This pin has an internal 0.5 to 5 M
W
feedback
resistor between XT and
XT
. If an external clock is used, this is the clock input pin.

Command Input and Option Control.
This pin is used as command and
option input when CMD is at the high level with
ST
low. If this pin is not used or
serial input is optioned, set this pin to "H" level. This pin has an internal pull-up
resistor.
Start.
Speech playback starts at the fall of the
ST
pulse. The I0 - I6 addresses
are latched at the rise of the
ST
pulse. Input a
ST
pulse when NAR goes to the
high level for channels 1 and 2. This pin has an internal pull-up resistor.
Channel Control.
Channel 1 is selected when the input is pulled high. Channel 2
is selected when the input is low. This pin has an internal pull-up resistor.
This pin is command and user-defined phrase input when parallel input is optioned.
This pin is serial data (command and address) input when serial input is optioned.
This pin is command and user-defined phrase input when parallel input is optioned.
This pin is used as serial clock input when serial input is optioned.
This pin is command and user-defined phrase input when parallel input is optioned.
When serial input is optioned, set this pin to "L" level. This pin has an internal
pull-down resistor.
This pin is command and user-defined phrase input when parallel input is optioned.
When serial input is optioned, this pin is a port output. The port output is controlled
by entering external silence insertion code.
This pin is command and user-defined phrase input when parallel input is optioned.
When serial input is optioned, this pin is a port output. The port output is controlled
by entering external silence insertion code.
This pin is command and user-defined phrase input when parallel input is optioned.
When serial input is optioned, set this pin to "L" level. This pin has an internal
pull-down resistor.
Ground pin.
Power supply.
Insert a 0.1μF ro more bypass capacitor between this pin and GND.
Supply voltage for writing data to internal OTP ROM.
Interface with voice analysis edit tools AR761 and AR762. Set to "L" level or leave
open during playback. This pin has an internal pull-down resistor.
